I found that SelectedBackcolor is not the only problem. ForeColor is another property being locked (always back).

My current workaround is setting EnableHyperlinks to .T. on MouseEnter and reverting to .F. on MouseLeave. It is not perfect but solves some of my problem. Please let me know if can you think of a better solution.

_vfp.EditorOptions='LQTk'

o=CreateObject('form1')
o.Show(1)

Define Class form1 As Form
	Height = 154
	Width = 267

	Add Object edit1 As EditBox With ;
		Anchor = 240, ;
		Height = 53, ;
		Left = 12, ;
		Top = 12, ;
		Width = 240, ;
		EnableHyperlinks = .T., ;
		ForeColor = Rgb(255,0,0), ;
		Value = "Click here: http://www.welkin.com.hk (EnableHyperlinks=.T. -> RED can't be shown)"

	Add Object edit2 As EditBox With ;
		Anchor = 240, ;
		Height = 53, ;
		Left = 12, ;
		Top = 84, ;
		Width = 240, ;
		ForeColor = Rgb(255,0,0), ;
		Value = "Click here: http://www.welkin.com.hk (On-Mouse-Enter/Leave Programmed)"

	Procedure edit2.MouseLeave
	Lparameters nButton, nShift, nXCoord, nYCoord
	This.EnableHyperlinks=.F.

	Procedure edit2.MouseEnter
	Lparameters nButton, nShift, nXCoord, nYCoord
	This.EnableHyperlinks=.T.
EndDefine
